No feedback from ***** Department

I filed a ***** complaint on 16/01/2024 with FNB Debi Card Dispute. The bank advised that they would respond to my request within the next five (5) business days. After that 5 days I visited the bank to find out what happened to the matter. There I am informed that it takes 30 and not 5 as stated in their letter. Well 30 days have passed and still no feedback
